SPECIFICATION forming part of Letters Patent No. 240,242, dated April 19, 1881. Application filed September 4, 1880. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH FLETCHER, a citizen of the United States, and residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Bellows, of which the following is a specification.

' In the drawings which are hereto annexed, Figure 1 is a perspective view of my improved nozzle. Fig. 2 is a top View. Fig. 3 is a longitudinal section, showing the nozzle applied to the bellows-frame.

Similarlettersreferto similar parts throughout the several views.

1 construct my nozzle A in the form of a flattened cone, with the upper and lower rear portions rabbeted, as shown at B B. The rabbet represent-ed at B extends outward to near the center of the pipe and forms ashoulder,against which tbeend of the center board, 0, of the bellows is placed. From the upper rabbet, B, extend arms 13, by which the nozzle is secured to the center board, 0, by means of the bolts to a. The upper rabbet also receives the end of the top board, D, of the wind-chest, the end of which rests against the shoulder thereof, in the same manner as that of the end of the center board, 0, against the lower rabbet, B.

To the under side of the center board is hinged the bottom board, E, while to the upper part of the nozzle is hinged the top board, D, and the Whole, with the exception of the extreme-outer end of the nozzle, is covered with a casing of leather and suitably packed to prevent any escape of air. The bottom and central boards are to be provided with the usual valves.

Havingthus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

In a bellows, the combination of the flattened conical nozzle A, having unequal rabbets B B on opposite sides, and sustainingarms B B extending from. the upper rabbet, the stationary center board, (J, bolted to said arms, and the upper and lower boards, D E, hinged respectively to the upper part of the nozzle and to the under side-of the center board, as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 16th day of August, 1880.
